Intro
I'm foremost a husband and father. Software has fascinated me since 2nd grade when I made simple games. That interest turned into over 15 years of professional software development across the full stack - from embedded systems to cloud infrastructure.
I founded Tietokanto Oy in 2022 to focus on what I do best: architecting and implementing scalable software systems, particularly for handling massive datasets. I've built data pipelines processing billions of rows, designed distributed systems, and optimized legacy software. The interesting part about optimization is that making software more efficient directly reduces compute resources needed - which means lower carbon footprint.
I do use AI tools in my work, but always with human oversight in the loop. Agentic development is still primarily suited for vibe-coding, which isn't my approach. There's also the consideration that AI tools can potentially waste significant amounts of energy, which conflicts with my focus on efficiency and reducing carbon footprint.
My toolbox includes Scala, Java, TypeScript, Python, and C++ for development. PostgreSQL and cloud-optimized PostgreSQL variants are my main databases, but I've worked with many others - Cassandra, Elasticsearch, ArangoDB. On the infrastructure side: AWS services, Terraform, Docker, Kubernetes. I've done full-stack web development with React, backend microservices with Spring and Akka, and DevOps automation.
The technologies vary by project, but the approach stays the same: understand the problem, choose the right tools, build systems that work efficiently and scale properly.
